(54)	Printing press, layered formation and making method thereof, and printing plate and making method thereof

(57) A layered formation, possibly used as a printing plate that is to be mounted to a printing press when performing printing, has a photocatalystic layer including a photocatalyst so that the surface of the photocatalyst layer is rapidly hydrophilized by irradiating with light having a lower irradiating energy. The layered formation or a printing plate includes an intermediate layer having two or more kinds of oxide semiconductors or a solid acid between a substrate and the photocatalyst layer.
